Re: [RFC] Explicit call-site send-by-ref syntax

Yes, this is an issue, and it'd be good to find a way to solve it. At least for count() and other "pure" (however pure can it be in PHP) functions it seems possible. But do not think "not using references ever" qualifies as a solution :) -- Stas Malyshev smalyshev@gmail.com
